MBP slow when connected to monitor and Bluetooth problems with Apple Keyboard

[Charizard007]

I have a MBP2018 connected to an external Samsung Monitor.

Whenever I connect the MBP to the monitor, it always gives off problems, it becomes slow and problematic to use, just random things not working well. None of these problems happen when the MBP is not connected to the monitor. I have to restart the MBP for the problems to go away, whereas without monitor, I don't need to restart it for weeks on end.


Also, the MBP is connected to external bluetooth MX Master 2S and bluetooth Apple Keyboard.
The mouse usually works fine. But the Apple Keyboard has problems every single day.. it disconnets and connects at random. It screws up my typing all the time. I have to restart the MBP for the issues to go away but that only seems to work 50% of the time.


It's really annoying and I cannot understand what is the problem. I'm thinking of resetting the MBP just to make sure...


Anyone else had experiences like this?

Hi mrgill92,

Following is a link to a description of the bluetooth errors I've documented on the 2018 MBP:

Thanks for linking that.

What you’ve described are EXACTLY the same things that have happened to me, multiple times a day, over the last 7-8 weeks that I’ve had the wireless keyboard and external monitor.

I see that resetting the machine didn’t solve anything.. so what can be done to solve this? I will try resetting the MBP tomorrow just in case...

Hi mrgill92,

Sorry to inform you of this, but nothing solves this issue nor the other issues I have with the 2018 MBPs, such as WiFi disconnects in addition to the bluetooth disconnects -- and I've exhaustively tried everything including erasing the SSD and downloading a new copy of the macOS from the Internet and installing only macOS with no other apps nor software nor any of my files/codes, and the 2018 MBPs still have these issues. I used to hope that the latest macOS/firmware update would solve these problems, but they haven't yet and I've had the machine since High Sierra 10.13.6 and its now on Mojave 10.14.5 Supplemental Update.

I suspect that since you are having the bluetooth errors, you probably are also experiencing the WiFi disconnects too, but since they are rare, random, and often intermittent (they fix themselves often in less than a minute but not always, as I've also waited over 16 hours and had the WiFi disconnect not fix itself), they are difficult to discover -- at times they mimic a slow Internet, at times AirDrop fails, Time Machine fails, Mac App Store updates fail, Software Update fails, etc. On the same thread and the same page 95 of posts that the link I sent you above you can also see my reports on the WiFi disconnects.

When I have bluetooth disconnects, instead of restarting the MBP I find it faster and easier to power off and then back on the bluetooth keyboard/trackpad...this causes the MBP to reestablish bluetooth connection to the device.

Let us know if you find a "solution", or also if you find the WiFi disconnections too. Thanks.

I was having the same issues, for me I narrowed it down to being connected to 2.4GHZ wifi.
As soon as I switched to 5GHZ wifi, my trackpad and keyboard stopped disconnecting and my computer ran smoother.
not sure what's going on but this worked for me.

I haven't experienced any WiFi disconnects, at least to my knowledge.

I reset the MBP and now the situation seems to be better. This is the first day and so far no problems with the keyboard disconnecting or anything. The mouse worked fine for hours and then experienced some lag, which I fixed by turning it on and off.

Will update in the next few days again.

Good for you! Glad you resolved your WiFi issues.

My WiFi/bluetooth disconnects, on the other hand, have always happened while WiFi is connected to 5GHz, 802.11ac, SNR>40dBm, 80MHz bandwidth, and on two different Apple Time Capsules, on an hitron router, and on an unknown router, so on four different routers in other words. My WiFi disconnects are related to the loss of DNS (Domain Name Service) information, information both from a standard DNS server as well as zeroconf (mDNS) local information. My WiFi disconnects are rare (2 to 20 times daily), random (while running any of about a dozen different programs, including Software Update, Mac App Store update, AirDrop, Time Machine backup, SMB-mounted disk drives improper ejections, rsync failures, ssh lost pipes, ping failues, iperf3 failures, git failures, subversion failures, etc.), and often intermittent (often fixing itself in less than a minute but I've also waited over 16 hours and not had it fix itself).

Good luck!

Wait... I do use an ethernet cable. But, I also share WiFi to my iPhone from the MBP's ethernet connection.

So maybe that was the issue? I haven't turned on Internet sharing yet after the reset... I'll try now.
